SPECIFICATION forming part of Letters Patent No. 624,954, dated May 16,1899. Application-filed September 27,1898. Serial No. 692,035; (Nomodel.)

To all whom it may concern.-

Be it known that I, CHARLES MARTIN MAL- LORY, a citizen of the UnitedStates, residing at Flandreau, in the county of Moody and State of SouthDakota, have invented a new and useful Improvement in Wire-StitchingMachines, of which the following is a specification.

My invention relates to improvements in wire-stitching machines in whichan inverting staple former, conveyer, and driver pivoted to anoscillating arm comprise the principal working parts; and the objects ofmyinvention are, first, to provide a machine of simplified constructionin which staples for-stitching or binding are formed and used in acontinuous manner, wire being fed into the machine from spools (by adevice not shown;) second, to provide a machine that will not clog, and,third, to afford plenty of room for handling books, pamphlets, (be.between the staple-driver above and the table beneath. I attain theseobjects by the mechanism illustrated in the accompanying drawings, inwhich t Figure 1 is a side View, and Fig. 2 is a front view, of theentire machine. Fig. 3 is a sectionalview of the former,conveyer,anddriver, showing how staples are formed on the upward stroke; and Fig. 4shows how they are set into work and clenched beneath. Figs. 5 and 6show the manner in which staple-former a and driver at are adapted tofit together.

Similar letters refer to similar parts throu ghout the several views.

The former Ct is milled or grooved to slide upon the driver d, thelatter being slotted to receive a coil-spring, which holds the former ain proper position bya spring acting against a pin set into the former.The latter is held from sliding off the driver d by the pin extendingfrom former a into and through the slot of driver cl. The former anddriver thus fixed together are held pivoted in side arm L by a rivet orpin passing through the hole in gear or toothed head of the driver cl,as shown.

The main casting, with table X and oscillating arm L, constitutes theframework of the machine, while the wire-cutter II, toothed rod R, theinverting staple former and conveyer a, with the staple-driver d,pivoted to and operated in conjunction with the oscillating arm L,comprise the principal working parts of the machine.

stapling-wire is fed into the machine from the right-hand side, as shownin Fig. 2 by dotted line P through a small hole P in shearlug m. (Shownin Fig. 1.)

-The length'of staples is regulated by the slide-stop S and theadjustable shear-slide m, which are held to place by screws, as shown.The wire in entering the shear slide or lug m passes through to stop Sjust in front of the which the staple is formed by the external former aon the upward stroke of arm L. In throwing the lever upward the formerCt is in the toothed rack-rod R in conjunction with the geared ortoothed head of the driver to where it is held firmly in position uponthe notch J of the arm L by coil-springs upon the rack-rod R in properposition for forming the staple. Just as the former a presses the wireon the anvil or internal former n the Wire is cut off by the shear h,which is operated by the plus i *6, Figs. 1 and 2. The staple is thenformed and carried down in former at until the latter strikes thepamphlet or book' Y, as shown in Fig. 4, where the continued downwardmovement of the staple-driver d forces it out of the former a throughpamphlet to die 0, where the ends of staple are clenched, as shown at P,Fig. 4.

The coil-springs on rack-rod R hold the former a in position at eitherend of stroke, one spring acting on the upward and the other on thedownward stroke when either forming or driving staples. nately on eitherside of the lug on main casting through which the rack-rod R passes.(Shown in Figs. 1 and '2.)

Having thus fully described myinvention, I claim as new and desire tosecure by Letters Patent 1. The combination in a wire-stitching machineof the staple-former a and the stapledriver d provided with a toothedpivot end, a slot and coil-spring the rack-rod R provided withcoil-springs, the oscillating arm L to which driver d carrying former ais pivoted for the purpose specified and substantially as shown,

anvil or fixed internal staple-former a, over verted with staple-driverd by the action of The springs act alter 2. The combination in awire-stitching machine of the rack-rod R, oscillating arm L, anvil n; ofthe shear h, shear-lug m, and stop staple-driver d, provided with gearortoothed S, substantially as shown and for the purpose end, the former a,and the anvil n, substanspecified.

tially as shown and for the purpose specified. CHARLES MARTIN MALLORY.
